Title:
  gnome-shell crashed with SIGSEGV in meta_window_get_monitor()

Status in gnome-shell package in Ubuntu:
  Confirmed

Bug description:
  Seems similar to some other reported crashes but with a different
  function call error. When turning back on a monitor the gnome-shell
  crashes. The crash does not occur until I attempt to turn the monitor
  on as it is happily playing sound and media buttons work with the
  screen off.

  Intel NUC with i7-5557U CPU and Iris 6100 graphics, happy to provide
  other information if helpful.
